| 摘 要： | 用微波法制备单分散、纳米水合二氧化锆，利用异相成核工艺在水合二氧化锆粒子表面均匀包覆一层Y（OH）3，制备出包覆型ZrO2（3Y）粉体先驱体．最后对煅烧ZrO2（3Y）粉体进行相结构分析，发现在室温下包覆型ZrO2（3Y）粉体中无m－ZrO2存在．结果表明；利用包覆的方法能将Y2O3均匀地加入到ZrO2中，提高ZrO2（3Y）粉体中亚稳定t－ZrO2的含量．

| Abstract: | Zro2(3Y) precursor which uniformly mixed with Y2O3 was prepared via hydrous-zirconia,which was prepared by microwave heating, coated with Y(OH)3 by heterogeneous nucleation processing. After ZrO2(3Y) precursor was calcined, its phase structure was analyzed by XRD. It wasfound that m-ZrO2 didn t exist in ZrO2(3Y) powder at room temperature. The results indicatedthat Y2O3 can uniformly be added in ZrO2 by coating means and the amount of metastable t-ZrO2 in ZrO2(3Y) powder can be increased. |

| Keywords: | heterogeneous nucleation means coating metastable t-ZrO2 |
